Personally, I think you should get rid of the West/East Germany superbonuses. The East Germany bonus is almost exactly the same as the Soviet occupation bonus, which gives anyone starting there a big boost. And by the time someone takes over the West Germany superbonus, it should be pretty obvious by that point that that person is winning :I

Guys, I have searched for how to fix the border effectively, but apparently I need to draw all the borders again.
Just to confirm before drawing, is there method that shrink the borders by 1 pixel so that the bonus borders will not overlap?
